Beschreibung

Returns the smallest number of days the first week of a year or month must
have in the new year or month. For instance, in the Gregorian calendar, if
this value is 1, then the first week of the year will necessarily include
January 1st, while if this value is 7, then the week with January 1st will
be the first week of the year only if the day of the week for January 1st
matches the day of the week returned by
IntlCalendar::getFirstDayOfWeek(); otherwise it will be
the previous yearʼs last week.
